You get a free credit when you sign up. You can use that to challenge anyone - subscriber or not.
If you want to play an experienced player but don't know anyone you can send the challenge to 'anyone' (no quotes) and someone will respond or 'everyone' in which case you'll get a different opponent with each turn.
Don't challenge me - just let me know your username and I'll send you a challenge so you still have your free credit.
